Hey there! If you’re trying to decide between 2 50 gallon electric heaters or a gas heater for your home, you’re in the right place. I’ve been down this road myself, researching water heaters for my own house, and let me tell you—it’s a big decision! Hot water is something we all need, whether it’s for a relaxing shower, washing dishes, or doing laundry. But choosing the right water heater can feel overwhelming. Should you go with two electric heaters for more capacity, or stick with a single gas-powered unit? I’m here to break it all down for you in a way that’s easy to understand, so you can make the best choice for your home. Let’s dive in and explore the pros, cons, costs, and everything else you need to know!
Why Consider Two 50 Gallon Electric Heaters?
When I was upgrading my home’s hot water system, I seriously thought about installing 2 50 gallon electric heaters. Why two? Well, sometimes one tank just isn’t enough, especially if you have a big family or use a lot of hot water. Let’s talk about what makes this setup appealing.
Using two 50 gallon electric heaters means you’re doubling your hot water capacity to 100 gallons. That’s a lot of hot water! If you’ve got a large household—say, five or more people—or you run a home business like a salon where hot water is constantly in demand, this setup can be a game-changer. Each heater can work independently, so you’re not relying on a single unit to meet all your needs. If one heater needs maintenance, the other can still keep the hot water flowing.
Electric heaters are also super easy to install. Most homes in the USA already have electrical systems in place, so you don’t need to worry about running gas lines or venting systems. Plus, they’re generally safer because there’s no risk of gas leaks or carbon monoxide. I remember feeling relieved knowing I wouldn’t have to deal with those worries.
But here’s the catch: running two electric heaters can get pricey. Electricity costs are often higher than natural gas, so your monthly bills might take a hit. Also, electric heaters tend to heat water more slowly than gas models, so if you’re using hot water faster than it can recover, you might run out during peak times. I learned this the hard way when my kids were all showering at once!
What Makes a Gas Heater a Strong Choice?
Now, let’s talk about the gas heater. When I was comparing options, the gas heater stood out because it’s so efficient at heating water quickly. If you’re like me and hate waiting for the shower to warm up, a gas heater might be your best friend.
Gas heaters use natural gas or propane to heat water, and they do it fast. They have a burner at the bottom that heats the water in the tank, and most models have a high first-hour rating (FHR), which means they can deliver a lot of hot water in a short time. For a family of four or five, a single 50 gallon gas heater might be enough, unlike electric heaters where you might need two to match the demand.
Another big plus is cost. In many parts of the USA, natural gas is cheaper than electricity, so your monthly bills could be lower with a gas heater. I was surprised to learn that even though gas heaters cost more upfront, they could save me money over time. Plus, gas heaters work even during power outages, which is a huge advantage if you live in an area with frequent storms.
But there are some downsides. Gas heaters need proper venting to release exhaust gases, which can make installation more complicated and expensive. You also have to be careful about gas leaks and carbon monoxide, so regular maintenance is a must. I made sure to schedule yearly checkups for my gas appliances to keep things safe.
Comparing Costs: Upfront and Long-Term
Cost is always a big factor when choosing a water heater. I know I spent hours crunching numbers to figure out what made sense for my budget. Let’s break down the costs of 2 50 gallon electric heaters versus a gas heater.
Upfront Costs
When I looked at prices, 2 50 gallon electric heaters were generally cheaper to buy than a single gas heater. A good 50 gallon electric heater costs around $500 to $800 each, so two would run you $1,000 to $1,600. Installation is usually straightforward, adding about $700 to $1,500 for both, depending on your home’s setup. Total upfront cost? Around $1,700 to $3,100.
A 50 gallon gas heater, on the other hand, costs between $600 and $1,000 for the unit itself. But installation can be pricier—anywhere from $1,000 to $2,000—because of the need for gas lines and venting. So, you’re looking at $1,600 to $3,000 total. If your home doesn’t already have a gas line, you could be spending even more.
Long-Term Operating Costs
Here’s where things get interesting. Electricity is often more expensive than natural gas in the USA. Running 2 50 gallon electric heaters means double the electricity usage, which can add up fast. Depending on your local rates, you might pay $50 to $100 a month for two electric heaters. Over a year, that’s $600 to $1,200.
A gas heater is usually cheaper to run because natural gas costs less in most areas. I found that a 50 gallon gas heater might cost $20 to $50 a month, or $240 to $600 a year. That’s a big savings compared to electric! However, if you live in a place like Portland, where electricity comes from hydroelectric power, electric heaters might be more competitive.

| Feature | 2 50 Gallon Electric Heaters | 50 Gallon Gas Heater |
|---|---|---|
| Upfront Cost (Unit) | $1,000–$1,600 (for two) | $600–$1,000 |
| Installation Cost | $700–$1,500 (for two) | $1,000–$2,000 |
| Total Upfront Cost | $1,700–$3,100 | $1,600–$3,000 |
| Monthly Operating Cost | $50–$100 | $20–$50 |
| Yearly Operating Cost | $600–$1,200 | $240–$600 |
Energy Efficiency: Which Wins?
I’m all about saving energy and keeping my bills low, so energy efficiency was a big deal for me. Let’s see how 2 50 gallon electric heaters stack up against a gas heater.
Electric heaters are super efficient at converting energy into heat—almost 98% of the electricity goes straight to heating the water. But because electricity is pricier, that efficiency doesn’t always translate to lower bills. Some newer electric models, like heat pump water heaters, can be even more efficient, using up to 70% less energy than standard electric models. I was tempted by these, but they’re more expensive upfront and need a warm climate to work best.
Gas heaters are a bit less efficient, with about 80-85% of the energy going to heat the water. Some heat escapes through the venting system, which is a downside. But high-efficiency gas heaters, especially those with an Energy Star label, can have a Uniform Energy Factor (UEF) of 0.67 or higher, making them pretty competitive. I found that these models could save me a few bucks each month compared to standard gas heaters.
If you’re using two electric heaters, you’re doubling the energy usage, so efficiency becomes even more important. I decided to look for Energy Star-certified models to keep my costs down.
Installation and Maintenance: What to Expect
When I was planning my water heater setup, I wanted something that wouldn’t be a hassle to install or maintain. Here’s what I learned about 2 50 gallon electric heaters versus a gas heater.
Installation
Installing 2 50 gallon electric heaters is usually easier because they don’t need gas lines or venting. Most homes already have the electrical wiring to handle them, but you might need an electrician to upgrade your circuit if you’re running two heaters. The biggest challenge is space—two tanks take up more room than one, so you’ll need a big basement or utility area. I had to measure my space carefully to make sure they’d fit.
A gas heater is trickier to install. You need a gas line and a venting system to safely release exhaust gases. If your home doesn’t have these already, the installation costs can skyrocket. I also learned that gas heaters need to be placed in a well-ventilated area, which limited where I could put mine.
Maintenance
Both types need regular maintenance, but gas heaters require a bit more attention. For 2 50 gallon electric heaters, you’ll need to flush the tanks once a year to remove sediment buildup. This keeps them running efficiently and extends their lifespan, which is typically 10-15 years. I also checked the anode rod every couple of years to prevent rust.
Gas heaters also need annual flushing, but you’ll also have to inspect the gas lines and venting system for leaks or blockages. This can be a bit nerve-wracking because of the safety risks. I made sure to hire a professional for these checks to keep my family safe. Gas heaters usually last 8-12 years, so they might need replacing sooner than electric models.
Safety Considerations
Safety was a huge concern for me, especially with kids in the house. 2 50 gallon electric heaters are generally safer because there’s no risk of gas leaks or carbon monoxide poisoning. The main thing to watch out for is electrical issues, like faulty wiring, which could cause a fire. I made sure my electrician double-checked everything during installation.
Gas heaters come with more risks. A gas leak could lead to an explosion, and carbon monoxide is a silent danger. I installed carbon monoxide detectors near my gas appliances for peace of mind. Regular maintenance is key to keeping a gas heater safe, so don’t skip those yearly checkups.
Space and Placement: Where Will They Go?
Space was a big factor for me when choosing between 2 50 gallon electric heaters and a gas heater. Two electric heaters take up more room—think about two big tanks side by side. My basement had enough space, but if you’re tight on room, this could be a problem. Electric heaters are also more flexible in where you can place them since they don’t need venting.
A gas heater is a bit bigger because of the venting system, but you only need space for one tank. The catch is that it has to be in a spot with good ventilation, and the venting pipes need to exit your home safely. I had to work with my plumber to find the right spot in my utility room.
Hot Water Demand: Meeting Your Needs
One of the biggest questions I had was whether 2 50 gallon electric heaters or a gas heater would meet my family’s hot water needs. Here’s what I figured out.
For a family of five or more, 2 50 gallon electric heaters give you 100 gallons of hot water, which is great for high-demand households. The first-hour rating (FHR) tells you how much hot water you get in the first hour, and with two heaters, you’re doubling that capacity. But electric heaters recover more slowly, so if you’re running multiple showers and appliances at once, you might need to stagger usage.
A 50 gallon gas heater typically has a higher FHR, meaning it can deliver more hot water quickly. For a family of three to four, this might be enough. If your household is smaller or you don’t use hot water all at once, a single gas heater could be perfect.
Environmental Impact
I care about the environment, so I looked into how these options affect the planet. 2 50 gallon electric heaters can be greener if your electricity comes from renewable sources like hydroelectric or solar power. But if your area relies on coal or fossil fuels, the environmental impact could be higher. Using two heaters also means more energy consumption overall.
Gas heaters burn natural gas or propane, which releases carbon dioxide and other gases. High-efficiency gas heaters are better for the environment, but they’re still not as clean as electric heaters powered by renewables. I decided to check with my local utility to see how my electricity is generated before making a final choice.
My Personal Experience: What I Chose
After all my research, I ended up going with 2 50 gallon electric heaters for my home. Why? My house didn’t have a gas line, and installing one would’ve been too expensive. Plus, I liked the safety of electric heaters and the fact that I could place them anywhere in my basement. The extra capacity was perfect for my big family, and I found Energy Star-certified models to keep my bills manageable.
That said, I totally get why someone might choose a gas heater. If you have a smaller household or want lower monthly bills, a gas heater could be the way to go. It really comes down to your home’s setup, your budget, and how much hot water you need.
Conclusion
Choosing between 2 50 gallon electric heaters and a gas heater isn’t a one-size-fits-all decision. I’ve been through this process myself, and I know it takes some thought. If you have a big family or high hot water demands, two electric heaters give you tons of capacity and flexibility. But if you want fast heating and lower monthly costs, a gas heater might be your best bet. Think about your budget, your home’s setup, and how much hot water you use every day. Check your local energy prices and consider the long-term costs, too. Whatever you choose, make sure it fits your lifestyle and keeps your home comfortable. Got more questions?
